[pcre-dev] pcre 8.12 + sljit

Hi all,

I rebased the code base to PCRE 8.12 and implemented some opcodes (newlinerelated \R . ^ $ and utf8-unicode related \P and xlass. You can download it from here:

http://sljit.sourceforge.net/pcre-8.12-sljit-all.tgz

Some performance resuls (this time on an x86-64 machine, and non-english utf8 text input: http://www.gutenberg.org/cache/epub/23756/pg23756.txt)

Note: since JIT compiling is a heavy weight optimization, it becomes efficient when the input size is big, the expression is frequently used or the matching requires deep recursion. Otherwise the compiling time can be longer than the runtime of pcre_exec.
